You may be familiar with the concept of "Schrödinger's cat 😻 ." Schrödinger, a physicist, proposed a theoretical experiment in which a cat is placed in a chamber with a small amount of radioactive substance. The substance may or may not decay, triggering a poison that would kill the cat. Until the chamber is opened, the cat exists in a state of uncertainty, being both dead and alive simultaneously. How does Quantum Physics differ from Classical Physics?   This thought experiment is often used to explain the fundamental principles of quantum physics, which describes the behaviour of matter at the atomic and subatomic levels. Quantum physics differs from classical physics, which describes the world at the macroscopic level, in more ways than just scale. Quantum physics often challenges our intuitive understanding of how the world works. SUPERPOSITION IN QUANTUM PHYSICS: In classical physics, an object is assumed to be in a single definite state at any given time (e.g., a c...

What is Quantum Entanglement? Quantum entanglement is a core concept in quantum physics that describes the peculiar relationship between two or more particles. When particles become entangled, their properties become correlated in such a way that the state of one particle is immediately connected to the state of the other, regardless of the physical distance between them. This means that measuring or manipulating one entangled particle instantaneously affects the other, even if they are separated by vast distances. The phenomenon of quantum entanglement challenges our classical intuitions, as it defies the notion of local realism and suggests the existence of non-local connections between entangled particles. It has been experimentally verified through various tests, including the famous Bell's theorem experiments, which provide strong evidence for the non-local nature of entanglement. Quantum entanglement plays a crucial role in the development of quantum technologies, such as qua...
